Hey guys!

I did this image for the GNOMON Gallery Show: COGNOSCO. Feel free to find out more information about the gallery here:


我这张图片是为Gnomon Gallery Show(COGNOSCO)做的。想要免费得到更多信息可以去这里:

So I used my old “Angel” model and just re-rendered it. Here is the final image:




I’ve also created a showcase tutorial article about how to create cool renders using ZBrush and Photoshop.

Let’s get started.



Preparing model and document.

Create new document with size twice as bigger as image you want in result. I do that every time I render any model in ZBrush because in the end I shrink the image at half size to get rid of “jagged” lines. I also press AAHalf button to see a preview for smooth-rendered antialiased image.





Set up your model on the canvas as you want to see it rendered. You will need masks for easier selections at further comp stage. So just go through all subtools one by one and export image with Flat render turned on.

在画布上设置好你想要渲染到的模型。你需要用遮罩在后面的合成阶段很容易地选择模型。这样把所有subtools里的模型一个一个用Flat render输出。


As result you get bunch of images with masking for each separate subtools.



There is also an alternative way to do that: Select each one of your subtools and fill it with a certain color from the ZBrush color palette. As result you get just one image with separated colors for different subtools. So you can group your mask colors depending on what kind of material you have. Here is how it works:



After that you may no longer worry about the model itself and just concentrate on rendering. Save document as *.zbr file. It will convert everything you have on canvas to pixols. You can use that as advantage and add more small details to the surface.

Use Directional Brush with Stroke set to DragRect and Texture turned off. Also make sure you apply it at Zadd or Zsub mode. I used alphas of damaged metal, bullet holes, some logos, etc. You can also add some dirt using Simple Brush with Spray stroke and mode set to RGB. Here is an example how it works


使用Stroke的DirectionalBrush设置为DragRect并把Texture关闭。还要确保你使用的是Zadd或Zsub模式。我用alphas制作受损的金属、弹孔和一些标志等,你还可以使用Spray stroke的Simple Brush添加一些污垢并设置为RGB模式。这里有一个例子如何制作:



One thing you have to keep in mind is that the light in ZBrush doesn’t affect the same way to MatCap as it does to standard materials. For example: If you change the position of light and use Best render with Shadows turned on for Standard materials you get the full response of your settings including color of the light, highlight and shadow orientation. Dealing with MatCap you get only shadow orientation because MatCap material already keeps information about color of the light. So I usually render bunch of images with different materials and light setup and just combine them together.

Here is my light settings I used for rendering this model.


有一件事你必须记住的是,ZBrush里的灯光对MatCap和对标准材料影响不同。比如:如果你在标准材料下改变光的位置并使用带Shadows的Best render将得到及时反应你的设置,包括光线、高光、阴影方向。处理MatCap你只是阴影方向,因为MatCap 材料已使有关的光的颜色信息。所以我通常把不同的材料和光的设置来把一大堆图像结合在一起。



You can play with Shadow Curve and Shadow Length setting. Depending on what kind of lighting you want to get you may want to adjust these values. Also if you have too noisy shadows you can increase rays amount to get smoother GI effect

你可以调节Shadow Curve和Shadow Length设置。根据你的灯光类型你可以按需调整这些值。此外,如果有太嘈杂阴影你可以增加rays数值来获取更柔和的GI效果。


I’ve found at ZBC tons of super-cool materials and I take my opportunity here to thank those people who do such great stuff and share that to ZBC community. To render this image I apply many different materials to the model and then combined the renders in Photoshop using blending modes of layers. Cool thing about MatCap I’d like to mention is that it’s easy to refine it if you’re looking for something more specific.



Here is a trick:

1.Create a square size document, 1024×1024 is fine.

2.Press “AAHalf” button to get Antialiased half sized image.

3.Create a sphere, subdivide it a couple times until you get it smooth, apply a MatCap you want to refine and export image. Make sure your preview shadows are turned OFF in render menu.

4. Exported image you can edit in Photoshop and do whatever you want from changing color to adding more highlights. If you want to stay in ZBrush just convert sphere to pixols and use ZBrush 2D brushes. To do that just turn off Edit Objet mode (“T” hotkey) and pick a brush you need.

5. Import your edited image of rendered sphere back in ZBrush. I just added more highlights and edited color a bit.

6. Go to Materials/Modifiers/Material Texture and replace old sphere image with a new one.




3.创建一个球体,把它细分几次使它光滑起来,按你要求应用MatCap来改进并输出图片。确保render>preview shadows是关闭的。

4.你可以在Photoshop里编辑你输出的图像并按你想要的改变颜色以便增加更多的高光。如果你想在ZBrush编辑只要转换成球体去pixols再使用ZBrush 2D brushes。要做到这一点需要关闭编辑展模式(快捷键“T”),并选择一个你的需要的刷子。


6.转到Materials/Modifiers/Material Texture并用新的图替换掉以前的。


You can go further. Combine this MatCap with ReflectedMap Material which is standard in ZBrush:

你可以进一步编辑。将这个MatCap的材质加上ReflectedMap Material:


Rendering and Comp.

I rendered the whole model with applied materials of different metals, some materials for the suit and skin. To reapply a material to your *.zbr document use Simple brush with “M” mode turned on. Select a material you want to apply. Set the stroke to DragRect and fill the model with the new material. Render image with shadows turned On and save it. As result you get bunch of images with different materials applied to it.

This is what I got:


我使用了不同金属材质、一些军事机甲和壳的材质符于整个模型,并渲染它。使用Simple brush(打开“M”模型)重新用一个材质给你的*. zbr文件。选择一个你想应用的材质想。将stroke设置为DragRect,填充一个新的材质给模型。打开render>shadows并将其保存。这样你就可以得到一大堆应用不同材质的图像。



I combined these renders in Photoshop using masks I exported from ZBrush earlier. It helped to quickly apply a material to proper parts of the model. During gathering all passes together I keep the image values pretty soft for easier control. I also try to avoid overdone shadows or highlights. You can always enhance shading/lighting/contrast after.

Here is an approach I use to organize materials using masks I rendered before:




To add or enhance reflections at metal surface I put rendered reflection pass on top of rendered metal pass and used mostly “Color Dodge” mode. You can also use Soft Light or Overlay mode depending on what kind of metal or light type you want to achieve, just don’t over-burn the image with too many Overlay passes ? You can also duplicate the layer and keep at the same comp Color Dodge and Overlay for better control.

Here is an example:




Regarding to different metal renders I mix the layers at Normal mode and just tweaking opacity of layer. When I’m pretty much done with general material look I move to scratches. Here is the trick:

As you can see from previous image I have a Base metal layer below Red metal. I did on purpose: if I use eraser on Red metal, the Base metal material will pop up. That is logically the same what happens in real world when a painted metal gets scratched. But there is a more flexible way to add scratches – it’s creating a mask. The advantage of that is that you can go back/forward in adding/removing scratches by switching color between black and white. This method is good for production texturing as well.




Here is a work-in-progress what I got using this approach.



As you can see it’s still pretty flat and boring in terms of color/tone and texture details. So after this I will add dirt, do a quick over-paint. You can play also with fog pass rendered in ZBrush and apply it as Multiple or Overlay pass to enhance feel of depth.

Here is a trick you can use when refining an image: duplicate flattened layer and set to Overlay Mode. Then use Blur filter, play with the radius and pick one what works better. After you’ll probably want to adjust levels and reduce pure black. The image below shows the effect. As you can see the image after applying blur at Overlay mode layer has nicer mood because of contrast and filtered color flow.




I did that overlay pass to all painted metal parts. After this I moved to other metal stuff and suit parts, refined the color here and there, painted a background, accentuated some highlights, added more dirt.

Here is work-in-progress image.





At this point I thought it would be cool to change the light and background to more warm tone. So I duplicated the layer (flattened image), applied blur to it. Went to HUE/Saturation, shifted the color to yellow. Then I refined background a bit. I used a smoke photo and distorted/twisted the image to create the effects.

Here is screenshot:

我认为它应该更冷,现在太亮了,而背景要更温暖的色调。因此,我复制图较平的图层,再模糊它。用色相/饱和度,让颜色偏向黄色。然后我优化一下背景。我用smoke photo和distorted/twisted来调整图创造效果。



I also wanted to desaturate a little some of the parts of armor, so I created HUE/Saturation layer control with mask.

Here where you go to do that:




And then click here to create mask:




This is pretty much all my tips & tricks for the process of rendering models using ZBrush and Photoshop. At the end I shrinked the image, adjusted a bit HUE/Saturation and added sharpness.

That’s it. Hope you liked that and hopefully you grabbed some useful tricks from this article.
